When I was a kid, I got a kick out of it when people would ask my father (who trained me) a question and he would say "what? Speak up, boy!" I thought he was putting me on, but he shot rifles ... not pistols, and he was half deaf from the experience.
It made him look like an idiot.
Unfortunately, he never used any kind of ear protection, so he didn't teach me that! Part of the reason was that he only shot rifles, and at that time there were few "inside the ear channel" options; it's hard to get a good cheek press with a rifle while wearing earmuffs.
But there were a few options; I found them, and used them, and ignored his "A Real Man Doesn't" remarks.
I took to stuffing cotton in my ears before bench-rest testing his rifles ... like the .30-338, the 338 Winchester magnum and the 7mm Remington magnum ... which he built over the years.
(He loved building rifles in experimental calibers. I was glad when he decided Jack O'Conner was his hero ... smaller, faster calibers, such as the 6.5-285, were easier on the ears!
Still, my hearing acuity has diminished over the years. And this is not a 'minor issue'. I'm now the grandfather who says "What? Speak up!" and my grandkids get a kick out of their idiot grandfather.
Doctors for Responsible Gun Ownership: Firearm Suppressors Fight Hearing Loss - Breitbart:
After showing that “significant, permanent hearing loss” can result from “a single exposure of 140 decibels or more,” DRGO points out that that “muzzle blast sound levels for most firearms (handguns, rifles and shotguns) range from 140 to over 170 decibels, more than sufficient to cause instant, permanent hearing damage.”
